:o Oh my, I can never make these again they were gone in two days. These were super-moist and AMAZING! The only thing I did differently was I used 1/4 cup of brown sugar and the rest regular white just because I like brown sugar. I also added probably a half cup of sweetened coconut flakes which didn't mess up the flavor at all but gave it a really nice texture. I also had to cook these way longer than recommended and checked on them every 2 minutes (might be due to the high altitude thing- Colorado). I definitely recommend these!

these were good. i ended up having to bake them for more like 25 minutes, but it might have been because i was using jumbo muffin tins. and they didn't have a huge banana flavor, but i blame that on the deceiving bananas i had--they were brown on the outside but not on the inside.
